jQuery Grid Plugin - jqGrid

Hi Tony

I want to trigger the beforeShowForm & onClose  for a show/hide columns dialog but they are never called the onClickButton is correctly called however (see below).

tradeGrid.navButtonAdd("#tradePager", {caption: "Show/Hide Columns",

 onClickButton:

function() {

   var options = { dataheight: 100,left: 400, width: 300 };

  $(

"#tradeGrid").setColumns(options);

},

beforeShowForm:

function() {

  if (typeof updateTradeGridId != "undefined" && updateTradeGridId != 0) {

   clearInterval(updateTradeGridId);

   updateTradeGridId = 0;

  }

},

onClose:

function() {

  if ($('#refreshTrades').attr('checked')) {

   updateTradeGridId = setInterval(

function() {

   $(

"#tradeGrid").setGridParam({ url: 'DataHandler.ashx?grid=trade&action=getTradeData&tsid=' + tsidParam + '&instr=' + instrParam + '&id_internal=' + instrumentDetails.id_internal + '&user=' + userParam + '&fromDate=' + thisFromDateStr + '&toDate=' + thisToDateStr + '&isBroker=' + isBroker + '&tradeType=' + tradeDetails.tradeType });

$(

"#tradeGrid").trigger("reloadGrid");
